Vintage Hat Box Suitcase 1920s Downton Abbey Era Hatbox

Lightweight textured brown suitcase- it isn't made of leather, but leather like. The inside is blue. a sort of plastic coated cardboard typical of the ear. The handle feels like leather to me, though it is a bit dried up. It has two buckles and a front locking mechanism- no key, though.

It says "Everlasting Lock" on it.

It measures 15 1/2" tall, 17" wide and 9" deep. It is in very good usable condition. Cant you see someone using it on a Downton Abbey set?
